I think GPs point is that this is how they're trying to spin it, but they're not explicitly saying it, and there are doubts whether it's actually true. For outside observers it's difficult to simply ignore all the embarrassing outages that cf has experienced recently and just accept that the company has suddenly solved all their issues by using AI and firing people.
I don't think the mistakes in themselves are damaging. What seems damaging to me is that cf has, on multiple occasions, repeated the same or similar mistakes right after they made major mistakes. This makes it seem like they're not learning from mistakes. Regarding the success of their business model, I can't make a meaningful statement about it, but is that really a convincing argument? If a business is successful, does that automatically mean their product is good?
